I really liked the High Yield Embryology and the BRS Anatomy. Medical Micro Made Ridiculously Simple is, by far, the best on in that series.
I also loved Lange's Medical Micro & Immunology. I used it almost exclusively for learning immunology. In general, the Lange review books are much more detailed than other review books and much less cumbersome than the dusty texts your faculty will require.
Take care,
Jeff
